He admitted to not seeing Punk's first WWE run from the mid-2000s to 2014 and based his opinion and criticism on the 46-year-old's ongoing stint.On the most recent episode of The Wrestling Outlaws, Vince Russo said that a rebel doesn't pander to the crowd and stated that it's ok for CM Punk to be focused on making money."There's a lot of pandering to the crowd, and I'm sorry, a rebel doesn't pander to the crowd. Bro, when you get older, let's face it, it's about money. You're not an idiot; you only got [sic] a couple of years left, so it's the smart thing to keep your mouth shut and collect that money as long as you can. But you can't expect me to buy into this character you're portraying," he said.One of Vince Russo's major criticisms of CM Punk's character is the fact that he is a rebel who always loses major matches. He compared Punk to Stone Cold Steve Austin, who, according to the veteran writer, won a lot more.Russo admitted that it is more of WWE's fault than Punk's, but he maintained that The Second City Saint isn't being fully authentic in his current persona.Please credit Sportskeeda Wrestling if you use this exclusive, and don't forget to listen to WrestleVotes Radio on Sportskeeda WrestleBinge.
